Question

I tried to extract the last line from a JTextArea and set it to a String
this is my cod:

JTextArea text = new JTextArea();
String text2 = text.getText();
int totalLines = text.getLineCount();
for(int j=0; j < totalLines; j++) {
   int end = text.getLineEndOffset(j);
   String line = text2.substring(end);
}

can someoane tell me where is the mistake? thanks

Your really close, just use JTextArea.getLineStartOffset to get the start of the last line, example:

int last  = area.getLineCount() - 1;
int start = area.getLineStartOffset(last);
int end   = area.getLineEndOffset(last);

String lastLine = area.getText().substring(start, end);
